First let me thank all of you who have offered suggestions on the Overheating prob on my 73 Vert v2.
I had tried self flushing the radiator, changing thermostats, re-tuneing, and my last hope was to pull the heads and change the head gaskets. On a lark I called our local radiator shop to check on the price of having the radiator boiled out, ($65). The lady asked me if it was overheating above or below 45mph. I said that I really had no problem driving around town but the minute I took it on the hwy it shot up to 230-250 degrees. when I brought it back down to 30-40mph it seemed to cool down some. She told me the radiator was clogged and to bring it in. After they examanded it they found that it was more than 3/4 clogged and it was not repairable. She couldnt replace it and suggested one of the Mustang parts houses. I called CJ Pony and ordered a new one for $300 which included shipping.
I installed it today and took it on a short trip down the freeway (about 40 miles) and the temp never got above 205 (195 degree thermo) same around town , it stayed twix 195 and 205
I am a happy camper!
I hope someone else finds this info helpful

Hey Ted!... First of all it is good to hear your problem has been solved without further damage to your engine... you know, i have been experimenting some "supposed" overheating problem in my I6 with still factory original Rad...

I´ve done everything you did with your car, even including changing the still factory original water pump, hoses, several flushes with those magic products and a new thermostat...

I havent had the chance to try my car enough yet but if it still does something asociable to overheating and with your experience i will go directly to a radiators place here, hoping that somehow they manage to redo the panel or something but wanting to keep the original frame of my rad...
